foam gasket?
I need a gasket to put under the basket of the speaker for sealing the air
in the box and dampening the vibration. But I only found foam gaskets, are they good for this purpose? thank you also for the latest reply and for the link to that RANE document. |

Closed cell foam is air tight but even open cell foam might work to seal a speaker system. If you buy foam rings from a company like Parts Express, you won't need to worry about the quality of the foam. |

I bought the rubber foam gaskets with closed cell, the ironmonger's told me that they are also acoustic insulating and don't mould. I've seen also some large panel of self-adhesive foam, and can I use them for damping the inside of the cabinet? Actually I'm using acrylic and polyurethane as damping material. |

You original post seemed to be referring to acoustic suspension seals for which closed cell foam would be best. Almost anything can be used for dampening material as long as it won't make noise when shaken. You ought to be able to use cotton batting, polymer fiber fill, foam, and probably other materials with similar success. Again if you buy your material from companies that list them for acoustic use, you should not have any problems. Even getting stuffing from fabric stores will probably be fine for dampening material. |

Madisound sells rolls of the thin self adhesive foam gasketing to go
around speaker frames. Check them out. Mark |
